I’ve been using a Surface as my usual travel PC for a while now – mostly Surface Pro (the first iteration) but also Surface RT and Surface 2. Microsoft has announced Surface 3 – is that a good buy?

Note: this is not a review of Surface 3. I intend to review it but have yet to get my hands on one.

First, a quick note on how I have got on with Surface to date. I love the compact size of the devices and the fact that I can do all my work on them. I find full-size laptops unbearably bulky now – though slim ultrabooks or small netbooks still have some appeal.

The main annoyances with my Surface Pro are the small SSD size (I have the 128GB model) and a few technical difficulties, mainly that the keyboard cover (currently the Power Cover) plays up from time to time. Sometimes it stops responding, or I get oddities like the mouse pointer going wild or keys that auto-repeat for no reason. Detaching and re-attaching the keyboard usually fixes it. Given that this is Microsoft hardware, drives and OS, I regard these bugs as disappointing.

Surface power handling is not very good. The Surface is meant to be running all the time but sleeps so that touching power turns it on or off almost instantly. That’s the idea, but sometimes it fails to sleep and I discover that it has been heating up my bag and that the battery is nearly flat. To overcome this, and to save battery, I often shut it right down or use hibernate. Hibernate is a good option – fairly quick resume, no battery usage – except that about every third resume it crashes. So I tend to do a full shutdown.

I find the power button just a little unpredictable. In other words, sometimes I press it and nothing happens. I have to try several times, or press and hold. It could be the contact or it could be something else – I don’t think it is the contact since often it works fine.

The power cover has stopped charging, after 10 months of use. It is under warranty so I plan to get it replaced, but again, disappointing considering the high cost ($199).

A few grumbles then, but I still like the device for is portability and capability. Surface Pro 2 seemed to be better that the first in every way. Surface Pro 3 I had for a week on loan; I liked it, and could see that the pen works really well although in general pens are not for me; but for me the size is a bit too big and it felt more like an ultrabook than a tablet.

What about Surface 3 then? The trade-off here is that you get better value thanks to a smaller size (good) and lower performance (bad), with an Atom processor – Intel’s low power range aimed at mobile computing – instead of the more powerful Core range. Here are some key stats, Surface 3 vs Surface Pro 3:

What about battery life? Microsoft quotes Surface Pro 3 as “up to 9 hours of web browsing” and Surface 3 as “up to 10 hours of video playback”. That is a double win for Surface 3, since video playback is more demanding. Anandtech measured Surface Pro 3 as 7.6 hrs light use and 3.45 hrs heavy use; the Surface 3 will fare better.

How much do you save? A snag with the Surface is that you have to buy a keyboard cover to get the best out of it, and annoyingly the cover for the Surface 3 is different from those for Surface, Surface 2 and Surface Pro, so you can’t reuse your old one.

A quick look then at what I would be paying for the Surface 3 vs Surface Pro 3 in a configuration that makes sense for me. With Surface 3, I would max out the RAM and storage, because both are rather minimal, so the cost looks like this:

Will I buy a Surface 3? It does look tempting. It is a bit less powerful than my current Surface Pro and perhaps not too good with Visual Studio, but fine for Office and most general-purpose applications. Battery life looks good, but the 128GB storage limitation is annoying; you can mitigate this with an SD card, say another 128GB for around $100, but I would rather have a 256GB SSD to start with.

However, there is strong competition. An iPad Air, I have discovered, makes an excellent travel companion, especially now that Office is available, provided you have a good keyboard case such as one from Logitech; you could get an iPad Air 2 with 64GB storage and a keyboard for slightly less than a Surface 3.

The iPad comparison deserves some reflection. The iPad does have annoyances, things like lack of direct access to the file system and non-expandable storage (no USB). However I have never encountered foibles like power management not working, and as a tablet it is a better design (not just because there are abundant apps).

It is also worth noting that there is more choice in Windows tablets and convertibles than there was when Surface was first released. Some are poorly designed, but ranges like those from Asus and Lenovo are worth checking out. In a sense this is “job done” since one of the reasons for Microsoft doing Surface was to kick-start some innovation in Windows hardware.

I hope to get some hands-on with Surface 3 in the next few weeks and will of course report back.

Microsoft has announced the Lumia 435, the first 400-series Lumia and the cheapest Windows Phone yet. The Lumia 532, also just announced, is an upgrade to the Lumia 530 and also pitched at a low-end market.

The phones are expected to go on the market in February at a price of around €69 (£53.50) for the Lumia 435 and €79 (61.50) for the Lumia 532.

I like the Windows Phone OS, and these devices look like great value. That said, the last aspirational Windows Phone was the Lumia 1020 in Summer 2013, with its fantastic camera. You would be forgiven for concluding that Microsoft has given up on high-end Windows Phone devices, which is unfortunate for developers since those are the devices likely to deliver more app sales.

If the Lumia brand has become strongly associated with cheap phones it will be hard for the company to convince customers that a high-end device is worth their attention in future.

We may get some phone news soon, linked to the launch of Windows 10; we may hear more at the event on January 21 in New York.

Data on human health has immense value. At an individual level, use of that data has the potential to enhance well-being and productivity, to extend life, and in some cases to avert disaster – such as prompting early investigation into a heart condition. In aggregate, more data on human health enables deeper medical research, especially when combined with other data about lifestyle, profession, location, diet and so on. Medicine is big business, so this is a business opportunity as well as (one hopes) a benefit to humanity.

There is also a dark side to this data. The more data an insurance company has on our health, the more likely they are to exclude the conditions we are most likely to suffer (defeating the purpose of insurance) or to ratchet up premiums for worse risks. Do we trust the industry, whether that is the IT industry or the insurance industry, to safeguard our personal data from being used against us?

The value of this data goes some way to explaining the IT industry’s obsession with fitness gadgets, an obsession that seems to go beyond the demand. I tried a Fitbit for several months, a wristband version. It is a great device, and I found the data interesting, but not enough to motivate me to keep the thing charged up and on my wrist, after the novelty wore off.

The reality is that most of us strike a balance between keeping vaguely fit while not allowing health concerns to dominate our lives. Coffee may be bad for you, but it is also a lovely drink; there is no point in extending life if you cannot also enjoy it.

How much health data, then, is too much?

These questions are likely to come to the fore as increasing numbers of health-monitoring devices come our way, especially multi-purpose devices that do health monitoring as one of several useful functions.

Enter Microsoft Band, which the company successfully kept under wraps until a couple of days ago. It’s $199, works with Windows Phone, Android and iOS, and packs in a lot of features, though its 48 hours battery life is too short for my liking (I am hard to please; my plain old watch has a 10-year battery life).

Band hooks into the Microsoft Health platform. There are apps for all three supported phones, and data goes into a cloud service which delivers “intelligent insights” for you. “The more you share with Microsoft Health, the more accurate and helpful your insights will become,” says the blurb. There seems to be a link with Health Vault, a service which provides for sharing of health information with health professionals; of course the company says privacy and security are highly protected.

If I buy one (only available in the US currently) it will be more for its non-health features. Microsoft Band (by linking to your mobile over low-energy Bluetooth) will do calendar alerts, email previews, plain old watch mode (so it is actually a smartwatch), facebook posts, Twitter messages, weather, and (on Windows Phone only), Cortana, Microsoft’s digital assistant.

There is a built-in microphone and you can speak to Cortana on the go. I’ve been trying Cortana since it was was announced at Microsoft’s Build conference earlier this year, and she/it is pretty good. Cortana is not just voice activated search; it is also an example of voice UI, so you can make appointments, take notes, or ask for directions. Its voice recognition and question parsing is impressive, in my experience, though of course not perfect.

As ever I have a developer’s eye on this and I think it is interesting. Voice recognition, touch screen, and semi-permanent link with a smartphone is a powerful combination, if Microsoft opens this up to developers; and I will find it surprising if it does not.

In fact, there are already third-party apps, if you count the Starbucks partnership. You can pair a Starbucks card with Microsoft Band, and pay for coffee with it. The method is rather low-tech: the Band will display a barcode which the Starbucks scanner can read, but still, it beats searching for your card or even pulling out your mobile.

And there is of course the health tracking aspect. There are a ton of sensors here:

Can Microsoft make a success of the Band and steal a march from Apple, whose Watch (which also does fitness tracking) is coming early next year? Apple’s device will be more beautiful, more expensive, and has more functions; but it will not work so well with Android or Windows Phone.

The big downer with Microsoft Band is that it is US only for the moment. Health Vault is already in the UK so we may see a UK release; the possibilities for global rollout are uncertain.

How many committees does it take to come up with a name like Microsoft Screen Sharing for Lumia Phones HD10? Who knows, but the product is a nice one. It lets you project from your phone to any TV with an HDMI input, using the Miracast standard.

Data is transferred to the device via Wi-Fi. You make the connection by tapping your phone on the separate coaster-like plate, which triggers the connection using NFC (Near Field Communication). The coaster talks to the device using Bluetooth.

The neat thing about this arrangement is that the main HD10 device will be close to your TV; it might even plug in at the back, out of sight. The coaster on the other hand can be on a table near your sitting position. You can come into the room, tap the coaster, and then view your photos and videos on the big screen in 1080p HD video quality.

At least, that is the idea as I understand it. Usability is key with this type of gadget, otherwise they do not get used, and this might just have it right.

The coaster thing can also be stacked on the main device as you can see from my blurry picture:

Concerning the name, all your worst fears about Microsoft taking over Nokia have been confirmed. Concerning the device though, all is well. I suppose that is the right way round, but it is really so hard?

Today Microsoft/Nokia made a number of announcements alongside the IFA show in Berlin, including a new wireless charging pad for its Lumia phones. Here is the new Lumia 830 while wireless charging.

The new pad glows, with the cool feature being that the phone can send alerts to the pad which cause it to flash. This means that if your phone is charging on a table at home, you can see when there is an alert and pick up the phone to check it out.

What can send an alert? I was told that anything which can appear in the slide-down notification area in Windows Phone 8.1 can also send an alert to the pad, though the user can customise which ones are enabled.

The concept is good, but the difficulty is that we receive so many alerts (most of little real importance) that the pad will be constantly flashing, unless you manage to filter it down things that actually matter; maybe missed calls, voice messages and texts?

Advanced options includes the recovery console, a command-line for troubleshooting with a few useful commands and access to files. There is also an option to Refresh or reset your PC, and access to System Restore which lets you return to a configuration restore point.

System Restore can be a lifesaver but in this case had been mysteriously disabled. Advanced start-up options like Safe Mode simply triggered Automatic Repair again.

Choosing Exit and continue to Windows 8.1 triggers a reboot, and you can guess what happens next … Automatic Repair.

You also have options to Refresh or Reset your PC.

Refresh your PC is largely a disaster. It preserves data but zaps applications and other settings. You will have to spend ages updating Windows to get it current, including the update to Windows 8.1 if you originally had Windows 8. You may need to find your installation media if you have any, in cases where there is no recovery partition. You then have the task of trying to get your applications reinstalled, which means finding setup files, convincing vendors that you should be allowed to re-activate and so on. At best it is time-consuming, at worst you will never get all your applications back.

Reset your PC is worse. It aims to restore your PC to factory settings. Your data will be zapped as well as the applications.

You can also reinstall Windows from setup media. Unfortunately Windows can no longer do a repair install, preserving settings, unless you start it from within the operating system you are repairing. If Windows will not boot, that is impossible.

Summary: it is much better to persuade Windows to boot one more time. However if every reboot simply cycles back to Automatic Repair and another failure, it is frustrating. What next?

The answer, it turned out in this case, was to look at the logfile. There was only one problem listed in SrtTrail.txt:

I looked up vsock.sys. It is a VMware file, not even part of the operating system. How can this be so critical that Windows refuses to boot?

I deleted vsock.sys using the recovery console. Windows started perfectly, without even an error message, other than rolling back a failed Windows update.

Next, I uninstalled an old vmware player, using control panel. Everything was fine.

The Automatic Repair problem

If your PC is trapped in the Automatic Repair loop, and you have no working backup, you are in trouble. Why, then, is the wizard so limited? In this case, for example, the “boot critical file” was from a third-party; the wizard just needed to have some logic that says, maybe it is worth trying to boot without it, at least one time.

Finally, if this happens to you, I recommend looking at the logs. It is the only way to get real information about what it going wrong. In some cases you may need to boot into the recovery console from installation media, but if your hard drive is working at all, it should be possible to view those files.

I spent a morning in Oxford taking some snaps and thought it would be fun to compare what a budget Windows Smartphone – the new Nokia Lumia 630 – can do versus the king of photography smartphones, the Nokia Lumia 1020.

Note this is not intended as a fair comparison; the 1020 costs around four times as much as the 630. It does show what you are giving up if you use a budget smartphone for all your snaps. In each case, you can click the image to see the full resolution.

Here is the Bodleian Library on the 630:

and on the 1020, using the 5MP version (the 1020 also stores a high res version of each image):

Next, Pembroke College on the 630:

The difference is more telling if you zoom in. Here is a detail taken from a picture of Broad Street on the 630:

and on the 1020:

What about the high-res versions of the Lumia 1020 snaps? Here is a picture of Oxford’s “Bridge of Sighs”:

Let’s zoom in to look at the sculpture on the bridge. This is from the 5MP version, which I’ve enlarged slightly:

Here is the same section taken from the high-res 34MP image:

I consider the improvement well worthwhile; it does pay to hang on to those high-res images for the pictures you most value.

I snapped this on the 630 too; here is the same zoomed-in and enlarged section:

Ouch!

Conclusion? The camera on the Lumia 630 is not too bad – for a cheap smartphone. The Lumia 1020 is something special and I am grateful to Nokia for delivering a smartphone with a camera good enough that I can leave a standalone camera out of my bag – noting that I am not a photographer, just a traveller who takes pictures. I have not used a tripod on any of the above; from my perspective, coping with camera shake is one of the characteristics I need in whatever camera I use.

I visited Microsoft’s “Apartment” in London, billed as a chance to see “Dragon’s Den star Kelly Hoppen’s apartment in the heart of Covent Garden kitted out with the latest Microsoft technologies,” and to include a “deep dive discussion” on Microsoft’s latest developer announcements.

How do you kit out an apartment with the latest Microsoft technologies? Apparently, you stick an Xbox One and a couple of PC screens in the living area, and upstairs in the study (a mezzanine floor), a PC, a Surface (not 3 sadly), and a Windows phone connected to a big screen.

There were certainly lots of screens, but nothing in the way of home automation, and after watching Microsoft presenters struggling to get the Xbox One to play the right kind of music, and later a shaky Skype demo, it is hard to enthuse over this particular setup.

For some reason, we were not shown any cool games on the Xbox One, nor cool apps on the Windows Phone other than the Cortana assistant which is not yet available in the UK. There was a demo of the new swipe keyboard in Windows 8.1 which inevitably saw the word “document” rendered as “cucumber”; a shame as I know from my own experience that this keyboard works very well, but demoing this kind of thing in public is only for the brave or the very well rehearsed.

We did see collaborative real-time editing on an Office document – not something home users generally do, but to be fair this was part of a business-oriented discussion which followed.

One feature which I had not previously been aware of was the ability of Skype on the Xbox One, in conjunction with Kinect, to follow the speaker around the room automatically. If you like pacing up and down while on Skype, this is a cool feature; perhaps it would be good for talking to excitable kids as well.

Takeaways? Let me put it like this. If you thought, perhaps, that the Xbox One has potential but feels (in software terms) not yet ready; or that Microsoft has no idea how to market to consumers; then there was nothing here that would change your mind.

As chance would have it, the Microsoft apartment is a few paces away from Apple’s huge Covent Garden store, and seeing the crowds eager to try the latest iDevices put the Microsoft event in perspective.

I took advantage of a recent US trip to purchase a Surface Power Cover, at the Microsoft Store in Bellevue, near Seattle.

The concept is simple: you get an external battery integrated into a Surface keyboard cover. The keyboard is similar to the second version of the Type Cover, though curiously without backlighting other than a caps lock indicator. The keys are mechanical which for most people means you can type faster than on the alternative Touch cover, though it is less elegant when considered as a cover rather than as a keyboard.

The trackpad is the same on all three second edition covers, which is to say, not good. The problem is not the trackpad itself, but the mouse buttons, which are NOT mechanical keys (they were on the first edition Type Cove). Given that you need to press and hold a mouse key for some operations, having a physical click on the trackpad buttons is particularly useful and much missed. Another annoyance is that you cannot disable tap to click, which means some mis-clicks are inevitable, though on the flip side it is easier to tap to click than to use the fiddly mouse buttons.

Having said that it is the same, I have noticed that the trackpad on the Power Cover seems a bit smoother and better behaved than the one on the Type Cover 2. This could be sample variation, or that it is new, or that Microsoft has slightly tweaked the internal design.

As you would expect, the Power Cover is heavier and more substantial than the Type Cover, though I find you notice the weight more than the bulk. Even with the Power Cover, it is still smaller and neater than a laptop. The extra rigidity is a benefit in some scenarios, such as when the keyboard protrudes over the edge of a table. The fabric hinge, which is a weak point in the design of all the Surface covers, seems to be the same on the Power Cover and I fear this may cause problems as the device wears, since the extra weight will put more strain on this hinge.

As with the other keyboard covers, if you fold it back under the tablet, the keys are disabled. In this mode the Power Cover is purely an external battery.

I used the cover with the original Surface Pro (it is compatible with all the models other than the original Surface RT). I understand that a firmware update is needed for the power cover to work; if so, it installed seamlessly though I did need to restart after connecting the keyboard for the first time. Everything worked as expected. If you click the battery icon in the notification area you can see the status of both batteries and which is charging, if you are plugged in; generally one one charges at a time.

I boarded my flight and noticed that the Surface is smart enough to use the external battery first, and then the internal, presumably on the basis that you might want to remove the keyboard and use the Surface in pure tablet mode.

It is impossible to be precise about how much extra time you get from the Power Cover, since it depends how you use the machine. It is a big benefit on the original Surface Pro which has rather poor battery life; extended battery life is perhaps the biggest real-world difference between the Surface Pro and the Surface Pro 2. Subjectively I have doubled the battery life on my year-old Surface Pro, which for me makes the difference between running out of battery fairly often, and hardly ever.

The Power Cover costs $199, which is expensive considering that you can get an entire spare Android tablet or Amazon Kindle Fire for less; but put in the context of the equally over-priced Type Cover, which costs $129, you can argue that it is not that much extra to pay. Prices from third-party sites will likely be lower once availability improves.

If you need it, you need it; and this must be the best way to extend the battery life of a Surface tablet.

The Surface keyboard covers are not perfect, and I still sometimes see an annoying fault where the mouse pointer or keys stop responding and you have to jiggle the connection or tap the screen a few times to get it back (I am sure this is a driver issue rather than a poor physical connection). Still, I put up with a few irritations because the Surface gives me full Windows in a more convenient and portable form factor than a laptop, and there is more right than wrong with the overall design.

Summary:

If you already have a keyboard and your Surface lasts as long as you need – forget it.

If you have a Surface that runs out of power with annoying frequency (probably a Surface Pro 1), this is worth it despite the high price.

If you don’t have a keyboard (for example, you are buying a new Surface) then this is worth the extra cost over the Type keyboard.
